THREAD-CARD HOLDER FOR SEWING-MACHINES.

SPECIFICATION forming part of Letters Patent No. 268,335, dated November 28, 1882. Application filed July 20, 1882. (Modeh) Patented in Germany March 11, 1882, No. 1,891.

To all whom it may concern:

Be it known that I, GUSTAV WIOKE, of Barmen,RhenishPrussia,'Germany,haveinvented a new and Improved Thread-Card Holder for Sewing-Machines, of which the following is a full. clear, and exact description.

The object of my invention is to provide a new and improved device for holding cards, on which thread is wound, on a sewing-machine in such a manner that this card can rotate freely to permit the thread to unwind from the same as rapidly as it is used.

This invention consists in a clamp adapted to hold a card on which thread is Wound in "such a manner that this card can be rotated very freely and the thread unwound as rapidly as it is required by the sewing-machines.

The invention further consists in the combination, with the arm of a sewing-machine, of a bracket-arm, in the outer end of which a rotary thread-card-holding device is held.

Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a perspective view of the upper part of a sewing-machine provided with my new and improved device for holding threadcards on a sewinganachine. Fig. 2 is acrosssectional elevation of the arm of the sewingmachine, showing the bracket-arm for holding the card-holding device. Fig. 3 is a cross-sectional elevation of the arm of the sewing-machine, showing a modified construction of the bracket-arm for holding the cardholder. Fig. 4 is a side elevation of the card-holding clamp. Fig. 5 is a side elevation of a modification, of the same, showing the card held therein. Fig.

. 6 is a side elevation of a modification provided with a spring. Figs. 7 and 8 are end elevations of, another modification, also provided with a spring. Fig. 9 is a front elevation of a card clamping device resembling the one shown in Fig. 4., provided with a detachable pivot. Fig. 10 is a longitudinal elevation 'of this pivot. Fig. 11 is a longitudinal elevation of a further modification ofa card-holder.

Some kinds of thread are not wound on wooden spools or bobbins, as is generally customary, but are wound on pasteboard cards, as shown atA in Figs. 1, 5, and 9, which cards can be made of any suitable kind of cardboard, bristol-board, thin pieces of wood, or any other analogous material. The thread is wound transversely on the same, and in order to facilitate the unwinding of the thread these cards must beheld in such a manner that they arm B in such a' manner that the pintleG pro-- jects through an eye at one end of this bracket-arm D, as shown in Fig. 2, which bracketarm can be locked at any desired inclination in a horizontal plane to the arm B by means ofa binding-screw, D. The outer end of the bracket-arm D is provided with a tubular vertical socket, E, adapted to receive the pivot F, projecting downward from the thread-cardholding clamp G. o

If desired, the construction of the bracketarm D may be modified, as shown in Fig. 3, in which case it is held in place by aset-screw, H, resting against the side of the arm B ofthe sewing-machine. But this construction may he modified as much as desired, and different devices may be used for holding the bracketarm in the desired position on the sewing-machine arm B.

The card-holding clamp G is provided with a transverse groove or slit, G, adapted to receive one end of the thread-card A, which card can be held within this groove or slit by means of a bi11ding-screw,J.

If desired, an intermediate piece, K, may he placed between the inner end of the screw and the card A, as shown in Fig. 5.

The binding-screw J may be dispensed with, and a locking or binding spring, L. may be used within the slit G, as shown in Fig. 6.

The clamp may consist of'two hinged jaws, M, which are pressed against each other by springs N N, or of two hinged jaws, M M, which are pressed together by one spring,.O, as shown in Figs. 7 and 8.

-In the device shown in Fig. 1-1 the card A is held by rotating clamps at the topand hottom, which clamps are pivoted in the ends of a U-shaped frame, P, which is held adjustably in a vertical standard, Q, on the arm 13 of the sewing-machine.

In place of attaching the pintle or pivot F directly to the clamp G, the lower part of the clamp maybe provided with a vertical sleeve, It, adapted to receive the upper end of a detachable pintle, S, the lower end of which is passed into socket E of the arm B in the usual manner.

It will be seen that all thedifferentconstruc tions of the clamps are so arranged that a card can be held, and the clamps holding it can be easily and freely rotated by unwinding the thread from the card. Preferably the top of the clamp is provided with a Wide annular 1 flange, T, under which the binding-screw J is located, and which covers this binding-screw,

so that the thread, in case it becomes slackened, cannot catch on this binding screw.

Having thus described my invention, What I claim as new, and desire to secure by Letters Patent, is-

1. The device for holding thread-cards on sewing-machines, made substantially as herein shown and described, and consisting of a clamp for holding the card and adapted to be freely rotated, as set forth.

2. The combination, with a sewing-machine,

of a clamp for holding a thread-card, which clamp is adapted to be rotated freely on the arm of the sewing-machine, substantially as herein shown and described,and for the purpose set forth.

3. The combination, with a sewing-machine arm, of a bracket-arm held on the same, and a rotary clamp for holding thread-cards held on the end of this bracket-arm, substantially as herein shown and described, and for the purpose set forth.

4. The combination, with a sewing-machine arm, of a bracket-arm held on the same, a binding-screw for holding the bracket-arm in the desired position, and a rotary thread-cardholding device held on the end of the bracketarm, substantially as herein shown and described, and for the purpose set forth.

5. The combination, with the sewing-machine arm B, provided with the upright pintle O, of the arm D, the binding-screw D, the socket Eat the free end of the arm D, and of a thread-card-holding clamp adapted to rotate in the socket E of the arm D, substantially as herein shown and described, and for the purpose set forth.
